An FX exposure calculator turns a list of future foreign-currency payments and receipts into a view of what is exposed to exchange-rate movement. The free FX exposure calculator needs no account to try. It shows the currencies involved, the value in a reporting currency and what an adverse rate move could cost.
What the calculator measures
The first measure is net exposure by currency. Payments and receipts in the same currency are combined before risk is calculated. If a business expects to pay US$500,000 and receive US$150,000, its net US dollar payment is US$350,000. A euro receipt is kept separate because movements in one currency do not cancel movements in another.
The second measure is per-flow risk. Each payment or receipt keeps its own date, amount and direction. The model uses that timeline when estimating a typical adverse move, so a flow due next month is not treated as if it had the same time horizon as one due next year. The currency totals and the flow-level view therefore describe the same position at two useful levels.
What to enter
Add each expected foreign-currency flow with three details:
Confirmed invoices can sit alongside forecast flows, provided the difference in certainty is kept in mind when reading the output. The paste option accepts a prepared list, while individual rows suit a shorter set of payments and receipts.
How to read the result
Start with the exposure by currency. This shows whether the business is a net payer or receiver and the current indicative value in the reporting currency. It is the amount affected by exchange-rate movement, not a loss.
Next, read the adverse-move figure. This estimates what the open position could lose under the selected scenario. The timeline shows which individual flows contribute to that amount. A range of outcomes then places the current value between favourable and adverse ends, making the direction and scale visible without presenting either end as a prediction.
The strategy comparison keeps the same underlying flows and illustrates open, partially covered and fully covered positions. It is evidence for comparing outcomes. It does not identify one choice as suitable for a particular business.
What the calculator cannot tell you
The calculator is a model, not a forecast. Indicative market rates can change, and the adverse-move estimate describes a scenario rather than the next market move. It does not know whether a forecast sale will happen, whether dates will change or how much uncertainty a business can carry.
The rates shown are not executable quotes. Forward figures are indicative and can differ from the rate available for a specific amount, currency and settlement date. The model also cannot replace a business's own cash-flow records, board policy or professional judgement.
Use the result to make the exposure visible, test consistent scenarios and support a conversation with BLK.FX. It is educational evidence, not financial advice or a quote. Open the free calculator to enter the flows.

Common questions
Do I need an account to use the calculator? No. The public calculator is free and can be tried without an account. An account is needed only to save and track a business position.
Does the result predict where exchange rates will go? No. It models the position and selected scenarios using indicative data. It does not forecast the market.
Can payments and receipts be netted? Payments and receipts in the same currency are netted. Different currencies stay separate because their exchange rates can move independently.
